Hi, I am new to the forum and don't really consider myself a collector, but I have more of an "accumulation" rather than a "collection" of about 20-30 knives.
Anyway, I picked up 3 folding knives at an auction last night and would like to know anything about them and help me figure out how to open one. The first (not pictured) is a common Camp King. The other 2 are clearly vintage bone and brass. the fatter one has 2 Chinese characters on it that I had translated and says "fish" "dog" and no other markings whatsoever on it. The skinny one has a star and "superior" visible while closed. I can't figure out how to open it. It isn't rusted closed, because I can squeeze the blade in tighter. Also, what is that little brass "dodad" with the hole in it on the side? could that be the way to release the blade? (I can't seem to get it to push/pull/slide in any direction)
Thanks for any insight on these!
